为探明由不同树种组成的森林对土壤肥力的影响机制,采集湘中丘陵区地域相邻、立地条件一致、年龄相近的马尾松+石栎针阔混交林、南酸枣落叶阔叶林、石栎+青冈常绿阔叶林和杉木人工林土壤(0~15、15~30 cm)进行理化性质测定。结果表明:杉木人工林两土层的容重均高于3种次生林,4种森林土壤具有南方丘陵区红壤典型质地粘重特征,均为粘壤土,但4种森林类型土壤各粒级颗粒百分含量存在一定的差异;各土层含水率的变化趋势基本一致,均表现为杉木人工林最高,其次是南酸枣落叶阔叶林和石栎+青冈常绿阔叶林,马尾松+石栎针阔混交林最低;4种森林土壤全N、全P、全K、水解N、有效P、速效K平均含量均表现为0~15 c...

In order to expiscate effect mechanisms of forest made up of different tree species on soil fertility, the soil samples of Pinus massoniana＋Lithocarpus glaber mixed forest, Choerospondias axillaries deciduous broad leaved forest, L.glaber＋Cyclobalanopsis glauca evergreen broad-leaved forest） and Cunninghamia lanceolata plantation forest in middle hilly region of Hunan province in 0~15 cm soil layer than in 15 ~ 30 cm soil layer were collected, which were similar in tree species geographical neighbor, site conditions and tree-age, and the soi...
